Hey, after seeing this vid on youtube http://youtube.com/watch?v=0rfL00UCANA I got extremely interested in timelapse photography. I tried to lookup some information on wikipedia but I still haven't found the right interval and exposure settings so I can get a smooth looking video. I want to try it at night so it will definitly be an exposure of approx 10 seconds and with an interval of 1 photo / 20 sec ??? Who will tell me what I need to know ?

Health Warning: I've never tried this so the following may be rubbish!

Freeze frame a few of the shots about 30 seconds into the video and the length of the headlight trails will give you the individual exposure times if you can estimate the distance between the lamp posts and the likely speed of the cars. At about this time there is also some traffic feeding in on the road at the right. Even though that traffic is going slower unless my poor old eyes are deceiving me individual cars are only represented by two (or possibly) three exposures and I get a sense that the interval between exposures is at least as long as the length of each exposure. Remember that the human brain is quite good at filling in missing details so you get the impression of continuous motion.

But does anyone have an idea with what software you can stitch them all together ?

I agree with gordon on this issue.
adobe Photoshop CS3 Extended has a feture that allows video output when compiling a bunch of images. this is done by clicking open images as sequence when you click a folder then "open"
you may need to click Window and then animation to open up your video editing timeline.
hope this helps.

I can see the idea of doing this if you don't have access to a video camera, but really ...this is just digital video with a very low FPS count.

There's no commonly available video renderer that can work with 6-12 MP per frame, so it has to be derezzed somewhere in the process. But even if you got a hold of one, there are no monitors to display such high resolution.

It then begs the question - why strain your shutter-mechanics by doing this primitive trick? The new Nikon D60 has this "feature" as well and it made me roll my eyes when I saw it..lol.

This is similar to offering a new animation program that will allow you to paint each frame separately and then display them fast, one after the other..and voila! animation! lol

Save your expensive camera and get a 300$ DV camera and record footage. Slap it into a video editor and get better results. Batch-remove every Xth frame to get this time-lapse effect. Alternately, increae the playback speed to 20 times normal.

For about 1000$ you can get the Hi-DEF DVs and not only do time-lapse but real movie footage and record sound too.
